Once it's done, you'll now have classes_test.png and packages_test.png in the folder. The packages image allows you to determine if your code modules are properly decoupled. The classes files shows you how twisted your class inheritance may be.

Django models

For Django specific projects, you can install a module called "django_extensions". It also uses graphviz to generate some cool charts but is very Django friendly so you don't have to manually remove Meta classes from your models.

-l uses the "dot" rendering layout by GraphViz (possible values are: twopi, gvcolor, wc, ccomps, tred, sccmap, fdp, circo, neato, acyclic, nop, gvpr, dot, sfdp. I found dot to be the only legible one, and most of them didn't work for me)
